1'0 a whom it 14; (fH/Mffll'll-I i The handle 12 may be arranged as usual so Be it known that I, EMME'IT W. STULL, 8, that it can he removed only when the ufl citizen of the United States, residing at Norl troller is in of? position. The drums A \vood,in the county oi I-l'emilton and Stnte of mid ll lnny hr of nz| (lesln'd type and are 5 Ohio, have invented certain new and usolul l1('!'l-\'l|z|\\'!1z!. seilih lizilulhl drums, thrdrum Improvements in Mot-m-Controlicrs, of which A controlling the motors l mid 2 through sothe following is a full, clear, and exact speciries und parallel positions, while the drum b on fication. controls iho m tors I-l and -l in (he srunc way.

The usual The j 2 t o ..1.n invention is to provide a reversing switch C is provided and is intercont-roller by which the motors may be con- 5 locked with the drum B hy menus of the disk trolled in a number of different ways and ar- I7, notch-pinto 1N, and swinging lever 19 so 15 ranged so that the full on position of the i that it can he moved only when the drum B controller under different circumstances may is in oil' position.

handle 23 is shown on the shaft bf'drum 1). Since the two extreme positions of .the drum l) are only to he used in emergencies, as because of the disabling of one of the motors,

5 stops 2-! are provided in the path of the fingcr '25 on handle 23 so that when the handle 33 is lolly in position on tho shaftot drum 1). said steps ll and linger 25 prevent movernent --l' the drum into either rt its extreme in ord r to move the drum into these cxtrenw [n.sltlullS the handle 23 nnist be raised slightly, as will be seen from Fig, 1,

so that the finger lfrwill clear the stops "4.

This prevents the inadvertent movement of The drum 1 thus provides for the connection of the drum A and B in series for slow speed city trallic, and in parallel for high speed suburban or intcrnrlmn trallic, and also pro vides f r the cutting out of either drum and its connected motors in case such cuttingcont should be necessary for any reason. When either drum is cut out, it and its motors are entirely disconnected, while the connections 'of the other drum and its associated motors ,are net'all'ee-ted in the slightest. By reason of the interlocks and the use of the same handle for the drums and l), the drum l) can be moved only when the main controller 3 drums A and. i3 and the reversing switch are in their oil' pcsitions.

I do Int wish to be limited to the exact structure here shownand described but intend to cmer in the following claims all those oi:-
